To all whom 'it 'muy conce/'21:

Be it known that l. JOHN C. Binnen, e citizen of the United States, residing at Chicago, in they county of Cook and State of Illinois, have invented treibt/ain new und lisei M oresent invention relates to cer trucksl and Raitioularly to trucks having holsters mounted for both vertical and endivise movements in respect to the truck side frames, and the invention directed to the lprovision, in en extremely simple .and elli- .lfcienti manner, of increased wearing; face or .surface between the bolster and columns of ille side iframes. f 'llie invention also involves other novel tentures, all of which will be hereinafter described and defined in the claims. ln the accompanying drawings which illustrate my invention, like characters iiidicatc like parts throughout the several views.

Referring to the drawings, 'Figure l is e view in side elevation with some .parts broken away, showing the frame end bolster of a' car truck embodying my invention; Fig. Q is a vertice] section teken approxi.- niatcly on thc line .r2 f1.'2 on Fig. l, Some parts yboingr broke-n away; Fig. 3 is n plan view showing,r a ortion of oneI truck side frame and one en( of the truck bolster; und Fig. 4 is a vertical section taken on the line '.r :1:4 on Fig. 3.

`motion bearing rollers Y.

have laterally extended flanges the ends o the truck holster 5,

vshove the same, the/opening 9 is considerably wider than the seid tr'ansoin, but n proximetely, the upper vhalf portion of t e seid opening is preferably of about the seine .vidth es the said transom and is formed with wearing surfaces l0 vwith which ehe wearing surfaces 1l on the expended ends of thc holster 5 are arranged to engage., 'Otherwise stated, the said n'eci'inif suriices l@ are formed on those portions oi the side frames which forni the columns like of seid trames. The oiiter ends of the holster src prefer ably formed with projcctino stop dances or lugs 1:2 adapted to engege me enter si es of the column il to limit theiendwise Inovements of the bolster transversely of the truck. rlhis bolster is to he inserted end ivise into working position, in respect to the side frames, hefoze the transom or cross tie 3 has heen applied, or when' the said transom is removed from the lower portions of the openings f2 to aiiford the necessarv clearance.

lie truck springs l, preferably arranged in n group of i'oui, are sented directly on the.

ends of the transom 3 and indirectly on the bearing' flanges 8 of said side framcs.- The combined spring cap and roller base 6 is supported by the springs i and have laterally spaced guide flanges 13- that embrace the upper portions of the holster columns 10, and thereby guide the said element @E for true vertical movements. The lateral motion rollers` 'i' are interposer'l between the -coinbined s ring ccp and roller base 6, and

the ends o the bolster 5, and engage snitiible concave or dished seats in the seid inem bers 5 and 6, in the well known manner coinmon in the commercial Barber trucks, whereby the holsteris yieldingly centered or held in iin intermediate position. When the springs 4 are sufficiently compressed or re-' moved, the combined spring csp and roller buse G may be dropped down below the wearingI surfaces l() and removed by n horizontal edgcwise movementout of the openings Q.

As the chief novel feature of this invention. l extend the wearing surfaces of the continuntions of the column wearing surv faces l0. 'The supplemental Wearing surgide.

gli

lil() lOh face 15 nearly doubles the frictional sur face engagement between the bolster and the truck side fra-nies. This additional wearing surface is important with all truck bolsters having either Vertical or endwise moveinents in respect to the side frames, but is especially important in connection with bolsters which have both of the said move-v ments, with the resultingwear. The integral brake hanger'braelrets 14. have perforated lugs l@ to which the brake hanger links are adapted to be connected by a'pin or bolt, not shown. By reference, partien-l -lar1y, to Fig. 3, it. will be noted that the wearing surface on the ends ofthe bolster are also increased longitudinally thereof, to give the required surface for engagement with the wearing surfaces-10 and 15.

In Fig. 1, the numeral l? indicates the tie straps, tlie inner ends of which are secured by rivets 1S and dowel pins or studs '19, the lugs 20 being cast integral with the side frames l. The dowel pins 19 are cast into the said lugs and engaged through perforations in the said straps.' This affords a very simple and highly efficient means for connecting the tie straps to the side frames.

,'What l claim is: l. A truck side iframe having columns and brake hanger brackets, both of Whch'are provided with Wearing surfaces for engagenient with a bolster.

ln a car truck, side frames and a truck bolster, said frames having columns and brake hanger brackets, loothV provided with bolster and said bolster being spring,r supported in said side frames with' freedom -for vertical and eiidwise movements.

4. ln a car truck, side frameshaving integral columns and brake hanger brackets, in ,combination with a truck bolster, a spring supported in said side frames, said columns and brackets both having wearing surfaces for engagement with said bolster.

In testimony whereof I aix my signature in presence of two Witnesses.
